JOURNAL-BOX STRUCTURE.

Application filed January 14., 1926. Serial No. 81,150.

The present invention relates to improvemen ts in journal box structures.

More particularly the present invention relates to journal boxes of railway cars and has for one of its objects the provision. of a. simple and sturdy construction which may be assembled and disassembled with a maximum of simplicity and which affords a maximum of safety.

A further object is to provide a journal box construction which may be secured to the side frame without bolts.

Further objects will. appear as the description proceeds.

Referring to the drawings- Figure l is a view in elevation of structure involving the present invention. said view showing a journal. box in service position relative to a car axleand a side frame;

F igure 2 shows the construction of Figure 1 with the journal box in such a position that the side frame maybe lifted from said box;

Figure 3 is a sectional view taken along the plane indicated by the 111O'\ s 8- 3 of Figure 1'; and

Figure t shows a slight modification.

The numeral. 1 indicates a car axle, the

numeral 2 indicates a side frame, and the numeral 3 indicates a journal box cooperating with said axle and said side frame. According to the present invention the journal box 3 and side frame 2 are keyed together in such a manner that they are inseparable in ordinary service but may be readily separated upon the removal of certain parts, which will now be briefly referred to. The numerals 4. l represent the removable brass and wedge such as are ordinarily provided for holding the journal box 3 in position relative to the axle 1. When said memhers 44- have been removed, the journal box 3 may be rotated relative to the axle 1 in a vertical plane including the axis of said axle 1, which is to say, in a direction transverse to the side frame 2.

According to the structure illustrated in Figures 1 to 3, inclusive, the two walls6 and 7 which embrace the journal box 3 are recessed, as indicated by the numeral 8, for the reception of the studs 9, one of which is disposed upon each side of the journal box 3. The journal box 3 is provided on its upper side with thevlugs 10-10, which limit movement of the journal box 3 transversely of the side future 2 but which permit a rocking movement of the ournal. box 8 relative to saidside frame 2. As noted above, said journal box 3. may be tilted, or rocked, or rotated, relative to the axle 2 when the members H have been removed, said rotation occurring around an axis disposed along the corresponding lug 10.

' Referring to Figures 1 and 2, itwill be noted'that when the members 4.-4 have beenv removed, the distance E in Figure 1 may be reduced to the distance E of Figure 2. Moreover, the distance A of Figure 1 may be reduced to zero, as shown in Figure2.

lVhen said distances have been reduced in this manner, the studs 9-9 will be removed from the recesses 88 and the side frame may be lifted from the journal box 3 and axle 2. I j

There is no slack in the looking or keying 'means in normal service. Neither is there any slack if the truck of which the side frame 2 is a member is lifted, as for example by means of a crane, so long as the lifting forceisjiapplied to the wheels, the axles, the

bolster, the side frames, or to any part of the truck outside of the right-hand lug 10, which forms a pivotal point for relative rotating between the side frame 2 and the journal box 3. Even though the lifting force were applied to the left of the righthand lug: 10, the members 4-4 would prevent suflicient rotating movement of the journal box 8 to allow disengagement.

lVhen it is desired to remove the journal box 3 from the side frame 2, the journal box 3 must be rotated relative to the side frame 2 a sufficient number of degrees to disengage the recesses 8 from the studs 9, the axis of rotation 'beingparallel with and along the corresponding lug 10. This rotation may be accomplished by applying an upward force to the bottom of the journal box in the region indicated by the character W, or by applying in any way a torsional force that will rotate the journal box on the said axis. Therefore, after jacking up the side frame and removing the members 4-4, if the journal box cannot be rotated by hand, a jack should be applied somewhere in the region bounded by the extremities of the space marked by the character N. Force may be applied in said region to unlock the box, as

shown in Figure 2, after which the frame may be raised vertically.

According to the structure shown in Figure 4, a slightly modified means is provided for locking or keying the side frame 2 to the journal box 3. The numeral 11 indicates a gib located on each side of the journal box 3, which gibs cooperate with the hook projections 12 on the two side walls 6-7 of the 1 portion of the side frame 2 which embraces the journal box It will be clear that the hook projections 12-l2 in cooperation with the gibs 11ll will effectually key the side frame 2 to the correspondingjournal box under service conditions. The sideframe may be lifted clear of the journalbox, however, when said journal box has been rotated in the manner discussed above in connection with Figures 1 to 3, inclusive. If desired, the lug 9 and recess 8 may be located on the outer side of the frame member 2, though such a construction would sacrifice the inherent locking features of the wedge and brass members 4l-.

Though certain preferred embodiments of the present invention have been described in detail, many modifications will occur to those skilled in the art. It is intended to cover all such modifications that fall within the scope of the appended claims.

What is claimed is 1. In a railway car, a side frame and ajournal box, said side frame and journal box having cooperating members for lockingsame against separation under service conditions, said ournal box being provlded wlth removable means for preventing the rotating of said journal box relative to said side frame, said locking members being of a size to clear one another when said journal box is rotated relative to said side frame to a predetermined degree in a direction transverse to said side frame.

2. In combination, in a railway car, a truck side frame, an axle and a journal box, said ourna]. box being provided with removable means for preventing rotating of said journal box relative to said axle, said side frame and said journal box being provided with locking means for holding same against separation under service conditions, said locking means upon said side frame and said journal box being limited in size sufficiently to clear one another when said journal box has been rotated relative to said axle to a predetermined degree in a vertical plane including the axis of said axle.

3. In combination, in a railway car, a truck side frame, an axle and a journal box, said journal box being provided with removable means for preventing rotating of said journal box relative to said axle, cooperative abutments upon said journal box and said side frame for preventing the lifting of said side frame relative to said journal box when said journal box is in normal position, said journal box being rotatable in a direction transverse to said side frame when said means are removed to permit said abutments to clear one another.

Signed at Chicago, Illinois, this 23rd day of December, 1925.
